In the past two decades, use of Fiber Reinforced Polymer (FRP) bars in reinforced concrete structures has been increasing, replacing conventional steel reinforcement, especially areas with adverse environmental conditions. This paper presents a literature review on bond behavior FRP to concrete, which includes studies their (i) instantaneous and (ii) long-term (durability) properties. work also...

High velocity oxy-fuel (HVOF)coating have shown high resistance to corrosion in fossil energy applications and it is generally accepted that mechanical failure, e.g. cracking or spalling, ultimately will determine coating lifetime. The use of HVOF thermal spray to apply coatings is one of the most commercially viable and allows the control of various parameters including powder particle velocit...

Resin bonding to zirconia cannot be established from standard methods that are currently utilized in conventional silica-based dental ceramics. The solution-gelatin (sol-gel) process is a well developed silica-coating technique used to modify the surface of nonsilica-based ceramics. Here, we use this technique to improve resin bonding to zirconia, which we compared to zirconia surfaces treated ...

Knowledge on durability of concrete/epoxy bonded systems is becoming essential as the use of these systems in applications such as fiber-reinforced polymer (FRP) in strengthening of concrete structures is be...

A novel acid-base HT-PEM consisting of PI-COOH and OPBI was prepared. The OPBI-50PI-COOH composite membrane delivered superior cell performance durability under low PA uptake due to the continuous hydrogen bond network between PI-COOH.

OBJECTIVES This study compared the durability of repair bond strength of a resin composite to a reinforced ceramic after three repair systems. METHODS Alumina-reinforced feldspathic ceramic blocks (Vitadur-alpha) (N=30) were randomly divided into three groups according to the repair method: PR-Porcelain Repair Kit (Bisco) [etching with 9.5% hydrofluoric acid+silanization+adhesive]; CJ-CoJet R...

Abstract The lower bond strength of FRP bars to concrete compared steel has remained an unsolved barrier the widespread use FRP-reinforced under extreme loading. Additionally, degradation between reinforcement and concretes in aggressive environments adds existing concern. In this study, innovative anchorage system comprised polypropylene pipe was used strengthen seawater GFRP after 250 days ex...
